When officers arrived, they found Young and Prince lying in the grass with numerous cuts to their upper bodies.

A neighbor told police he was sitting on the front porch of his home talking with Young and Prince when they noticed Kinsey walking down an alley, according to the police report. The witness said they thought Kinsey was acting suspiciously and they decided to confront him.

According to the report, Kinsey dropped a bag of groceries he was carrying, pulled out a machete and stabbed the two men several times.

“The two walked out and approached him, and there were some type of words exchanged, and the witness said the suspect pulled out a long knife we believe was a machete,” said Sgt. Daniel Grubbs of Fort Smith police.

The neighbor told police he knew where Kinsey's mother lived. When police arrived at her home, at 524 S. 17th St., Kinsey was found inside, along with a machete in the garage. He was arrested and taken to the Sebastian County Detention Center.

"You can't explain evil behavior like that," Grubbs said. "A witness gave the comment that he heard during the confrontation with the two that (the) suspect made a mention of something to the effect that Satan is within him."

Police say Kinsey had no prior involvement with the victims. They believe the attack was random.

"If there is any good thing that came out of this, the person we believe absolutely responsible for this is in custody and will have to answer for his actions," said Grubbs.

Police said a 15-year-old and a 2-year-old were inside the neighbor's home.
